Hops Alpha Acid Table 2009

Saturday, February 27th, 2010

Updated for the 2009 harvest.  New varieties added – thanks to everyone who wrote in!

Alpha Acids from hops contribute to the bitterness in beer. During the boil alpha acids are isomerized and increase international bittering units (IBUs). This site has an IBU calculator.

Hops also contain beta acids, which contribute to aroma only. The more alpha acids the more bittering potential per ounce. For example, one ounce of Northern Brewer (8.5) is roughly equivalent of two ounces of Domestic Hallertau (3.9) in terms of bittering potential.

This chart is a general guideline only. The actual AA varies from year to year depending on the weather, harvest conditions, and storage.

  5. I grow 4 varieties (cascade, centennial, EKG and nugget). I brew almost exclusively with these but have no idea what the %aa is. Does anyone know an easy method of estimation? How accurate is the chart above?

  6. I believe you have to have a sample sent to a lab for analysis.

    The chart above represents averages from our sample data. No one has ever written in about a specific error, and in my experience when I see recipes or buy hops, the numbers line up reasonably well. AA values could vary by year, but even by grower or field!

  7. What about Galaxy Hops?

    By Paul on Aug 14, 2012

  8. Galaxy – Looks like an AA ~13.5

    Lots of people seem to like them:
